The hybridisation of atomic orbitals of nitrogen in are
(A) sp, sp3 and sp2 respectively
(B) sp, sp2 and sp3 respectively
(C) sp2, sp and sp3 respectively
(D) sp2, sp3 and sp respectively
No. of hybrid orbitals = Total no. of sigma bonds +lone pair of electrons. The no. of sigma bonds in are 2,3 and 4 respectively. So the hybridisation is sp, sp2 and sp3 respectively.
